Dab tsi yog cov kev ceev faj rau kev ua haujlwm ntawm txhuas pcb coj substrate?

1.mechanical ua

Kev nqus ntawm aluminium substrate yog OK, tab sis tom qab drilling, tsis muaj burr pub nyob rau hauv ntug ntawm lub qhov, uas yuav cuam tshuam rau kev ntsuas siab.Kev tawm cov duab yog qhov nyuaj heev.Thiab cov duab ntawm kev thov rau kev siv qib siab pwm, kev tsim pwm yog kev sim ua ntau, uas tseem yog ib qho kev nyuaj rau txhuas txheej.Tom qab cov duab ntawm cov dej ntws yaug, qhov kev thov ntug yog zoo nkauj heev, tsis muaj burr, tsis txhob kov cov tawv tsis kam txheej ntawm ntug ntawm lub phaj .Txhais siv cov hom kev ua haujlwm, lub qhov los ntawm txoj kab, cov duab los ntawm lub txhuas saum npoo, Circuit Court board punching quab yuam raug txiav qis, thiab lwm yam yog cov lus qhia. Tom qab txhawm rau txhawm rau lub hom, lub warpage ntawm lub rooj tsavxwm yuav tsum tsawg dua 0.5 %.

2. Suavteb

Tom qab etching, txoj kab yuav tsum dav yuav tsum ua tau raws li cov cai ntawm cov neeg yuav khoom kos duab. Cov seem uas yog tooj liab tsis pub, lossis tuaj yeem muab nws rab riam txiav tawg. Cov riam yuav khawb cov rwb thaiv tsev txheej, ua rau muaj hluav taws xob thiab tiv thaiv hluav taws xob hauv qhov ntsuas hluav taws xob.

3.Txoj kev tsim cov kab them nyiaj dav dav

Copper thickness, kab dav yuav tsum tau them nyiaj, txwv tsis pub tom qab etching kab dav dav tawm ntawm lub siab tsis kam, cov qhua tuaj noj mov tsis tuaj yeem txais, cov kab ntawv them nyiaj dav dav yuav tsum muaj kev cuam tshuam.

4. qhov sib txawv ntawm luam ntawv ua hauj vuam

Cov duab kab ntawv tom qab cov kab tooj liab tuab yog qhov txawv txav, luam ntawv tsis kam vuam yog qhov nyuaj, hla, cov tuab tuab thiab cov neeg muas zaub tsis dhau.Yuav ua li cas luam tawm txheej ntawm roj ntsuab kuj yog ib qho nyuaj.

5. tag nrho cov txheej txheem ntau lawm tsis pub so ntawm txhuas hauv paus

Aluminium puag saum npoo los ntawm kev sib chwv tes, lossis dhau los ntawm qee cov tshuaj siv tshuaj yuav ua rau muaj kev txhim kho saum npoo, blackening.Qhov no yeej tsis tuaj yeem lees txais, thiab qee tus neeg yuav khoom tsis lees txais aluminium puag saum npoo los ntawm kos.Yog li tag nrho cov txheej txheem tsis kov, tsis txhob kov lub aluminium substrate nto kuj yog ib qho kev nyuaj hauv kev tsim cov aluminium substrate.

LED aluminium substrate cov khoom lag luam tawm, qhib kev txhim kho ntawm tshav kub dissipation daim ntawv thov kev lag luam.Qhov rau qhov zoo tshaj plaws tshav kub dissipation ntawm LED aluminium substrate, aluminium substrate muaj qhov zoo ntawm tsis tshua muaj thermal tsis kam, lub neej ntev, voltage tsis kam thiab yog li.With kev txhim kho ntawm kev tsim thev naus laus zis thiab khoom siv, cov khoom lag luam nce nrawm tshaj tawm kev txhim kho, thiab tom qab ntawd nthuav cov thov kev lag luam ntawm LED teeb pom kev lag luam.Yog li kev lag luam teeb pom kev zoo, teeb pom kev zoo sab hauv tsev.Thaum qhov xwm txheej tag nrho, LED txhuas txheej hauv ob peb xyoos tom ntej tseem yuav muaj kev kub ceev ntawm kev loj hlob, ushered nyob rau hauv ib lub sijhawm ntawm kev loj hlob sai.

Qhov saum toj no yog cov ntsiab lus ntawm cov teeb meem xav tau kev coj ua hauv kev tsim cov teeb txawb LED txhuas txheej, Kuv vam tias yuav pab koj, peb yog tus kws tshaj lij PCB txhuas ntawv chaw tsim tshuaj paus hauv Suav teb, txais tos tham!
